sorry for late answer you have to try some LED-Config ( better name GPIO Config) settings inside rk322x-config tool and always reboot after every change, it should be support by kernel 5.x , else you can try legacy image ( with kernel 3.xx)

Thank You , ok switching things by adding a part of it

Thank you ok understandable wifi enable and GPIO state is clear for me also the SDIO part , i done some testing with Martin Blumestangl (xdarklight) on AMlogic 805 (nand and he help me with wifi enable , had a rtl8723bs with inverted signial) , but its not clear how a armbianENV can change /switch dtb things ok that was new for me that script do autodetect and that after config you have do start again the config sometimes

I have a more educational question , if the answer is too long or not appropriate please also PM me What does the right led-conf from rk322x-config have to do with the wlan chipset pins and why can't we separate them from the LED config ? How can the DTB be changed through the armbianENV.txt or must all information be present and these options are just a switch ? Can you maybe add in the rk322x config some information about the LED config so that we have a clue which wlan chip is activated (maybe an additional information page in the tool) ?

that a little unusal chip but linux compatible normally 8703 is part of 8xxxu standart linux libary https://kernel.googlesource.com/pub/scm/linux/kernel/git/jes/linux/+/rtl8xxxu-8188eu/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h "line106 " but i found also some guys that have a driver at github for building yourself https://github.com/java-batista/rtl8723cs

it looks like you already open your box , please send also the Wifi chip code . Maybe your wifi chip is not support by linux

inside linux goto /boot open with nano or other editor armbianEnv.txt add the new line cpu-stability save and reboot

yes red are UART please use 3,3V on you ch341 adapter rx tx should be cross --> , tx form usb to rx from board , and rx from usb to tx from board , GND to GND you can not break anything with change of Baud rate , try both and you are fine the text that run automaticlly on UART is the serial log , when nothing or only some unreadable thing is show in putty please change baudrate than copy the text from putty or other tool and post here for jock , also ANdroid will produce a log on UART ( with some diffirence) many of this serial log also in android terminal demsg log i dont know the usb port order , for multitool over USB the port is normally irrelevant ,some box need normal USB , some the USB otg , some box hasnt the usb otg

Hi N3O i think there a missunderstanding both are right it depends on what you want the real first boot loader talk at 1.5M than the UART get change by the bootloader from NAND or SD card or android to 115200 you only need to UART -> UART-USB-> USB of windowsPC or linux and a tool like Putty or Kitty you dont need connect UART back to box or male male cable for normal Logs the male male cable only for hard flash new bootloader or recovery with another PC with a rockchip tool

last picture right below corner 8 or B JG22 .....MW or NW.... . chip please google that this should be the flash memory

hi eMCP is RAM and Flash on one Chip most time , --> when you have only one big chip beside the CPU NAND and eMMC is more tricky but its look the first picture , with the not solder Area ist the place for NAND ( often the NAND ships have many pins on both oposide ends) to be really sure please look at the big ship below the AMS1117 power regulator some hint the 4 smaller chip are the RAM (on top and below board)
